The joy of being a kid. Relentless expressions of sorrow, joy, anger, confusion, inability, hopelessness and so on. When we grow up, we increasingly hide our feelings for all sorts of reasons. We regulate these expressions, carefully selecting the suitable situation to let go of these emotions which are waiting to get out. Some don't spit it out at all and prefer to keep it by themselves. This often leads to a deterioration of mental health. But is this feature integral to what defines an adult? Is it common to consider this 'restrictive' trait as part of adulthood or is it just how we are brought up, to think as such? I think so, for better or worse.
